I must sadly admit, that Kai’s apartment shouldn’t be called even a one third of the penthouse.
First thing - the entrance to apartment was through the restaurant’s facilities (that looked to be really unclean). The worst thing about apartment were small ants, running everywhere in the kitchen, notoriously coming to my dog’s food bowl. It was impossible to wash the dishes (not even saying about cooking), cause there were plenty of ants in the sponge, on the kitchen table etc.
Second thing - the water. Tap water was not flowing smoothly. It was necessary to open all the taps at once to make it flow in one place (what was especially uncomfortable in the kitchen, that was on a higher floor than the toilet with other taps).
Third thing - the blind in the bathroom was cut on a half, so it wasn’t fulfilling its role - when you’re taking a shower, all the neighbours can see you throughout the window.
Unfortunately I don’t recommend.
